I've lapped every chip I've had the last few years. I haven't done this one yet. The contact looks good but the temps indicate mines not flat either. With 8 deg between cores I think mine is in need of a good lapping too.

It would seem so. After watching temps for a few mins I found that the "worst" core on my 2500k is 12c hotter than the coolest core. Thats just crap manufacturing on intels part. I mean seriously... £180 and intel can't even put a even metal plate on the core?

so what is the max safe vcore without killing these things? 1.45v? 1.50v?

Somebody hasn't read Page 4, have they I've heard about plenty 2600/2500k CPUs dying with 1.55-1.6v. For 24/7 use I would not go higher than 1.45v. Its common scence, 45nm CPUs intel said absolute safe max voltage is 1.45v but of course that envelope was pushed a bit - 1.475-1.5v, 32nm makes sence absolute safe max 24/7 voltage would be around 1.42v, but again pushing the envelope a bit around 1.46v shouldn't do any harm, assuming you are using a good cooler.
